Appli ation filed April 2, L914. sfial N0. ssa'o ss'f To all whom it mrzy concern:

I Be it known'that I, EA L E RT a citizen of the United States, residingaat East Liverpool, in the countylof Qolum machinery and more particularly to a maf chine for straightening and planishing wire or metal rods. v t H r v The primary object of this invention is Y the provision of a machine for straightening and planishing metal rods I .or' wire, which has been formed in coils or otherwise bent to destroy the straightnessof the same, which machine embodies a rotatable frame carr inmwire .en a in convex roller dies .b b b b set at an angle to each other'whereby their' spiral rotation will feed the wire, being straightened, through .the machine; and (to mount these rollerdies in staggered position along the longitudinal: axis ofthe. ro-. tatable frame to flex the rod orwire in all directions to straighten it. U With the foregoing andv other objects inview this invention consists in such novel features of construction, combination and arrangementlof parts as willbe hereinafter more fully described,"illustrated in the accompanyingf drawings and claimed.

Indescribing the invention in detail ref v erence will .be had to the accompanying. drawings wherein like characters of reference designate -like or corresponding :parts throughout the several views, and in which: A I I v i Figure 1 is aside elevation .of the im proved wire straightening planishing machine. Fig. 2 is 'a diagrammatic end view of the rotatable frame .showing the wings formed thereupon. Fig. .3 is a vertical sectionalview through the machine. Fig. 4: is a detail plan View of the roller-dies I and the means of mounting ,the same] Fig. 5 is a partial sectional View on the linev of Fig; 1 showing the .rollers-inelevation.

Fig. 6 is a sideelevation ofa guide forthe l wire which is being strai'ghtened. Figs'7 is a front viewaof the wire guide shown in 1 Fig. (3, and Fig. Sis a diagrammatic view showing the angle: at which; the" rollers are disposed during" the operation of the machine' Referring Tnioreparticularly to the drawings, 1' and 2 designate pillow blocks, which have bearings formed upon their upper sur faces, .in which hearings. are; rotatably journaled thehollowfsliafts and 4:, The holiqw shafts 3 i and :4 proj ect' outwardly from the", ends- 0f frame 5, which frame has Wings j G na 7 formd on diametrically opposite'cor'ners thereof. I The wingsl o and 7 are provided with laterally extending openings 8 which receive =the'lugs j9. The

lugs 9 are formed uponsleeves 10,- which sleeves are mounted adj acent the, inner faces of the wings. The sleeves "lOr iare rigidly; held 'in place by means of setfscrewsll which pass int'o the openings 8, andhave their innerterminal, ends threadably Q011 nected to thelugs 9'as is clearlyfshownln' Fig. 5 0f .thedrawing's. The heads 12, of the set screws '11 are provided fwitlr annu lar flanges 13,",wl1iel1 .fiangesabntthev outer facesfof the wings Q 7 and bind thereagainst holding the lugs 9 securely posi tioned within theiopenings 8, The con iso nection between thefsl'eeves LOaIid the wings 6 and 7, by thefset screws 11, willQPermit of the sleeves being spaced" horizontally to accolninodate the various sizes of round metal rods or wires-which itfis desired to straighten. The sleeves lOhavethe shanks 15 0f the roller supportingtension forks 16 slidably seated therein. 1

The shanks l5 ofthe roller supportingforks 16 arelexternally screw threaded and provided Ywith key-ways extending" longitudinallyftherein in which are slidably seated the keys .or feathers 18, which ar'e car-j.

ried by the sleeves These keys v18 being slidably seatedwithin the key-ways .17, will permit of the sliding adjustment. of the shanks within the sleeves but will prevent 101,

their rotation therein. The adjustment of the shanks 15 within the sleeves 10is controlled by nuts 19, which have reduced por tions. 20 formed thereuponl The reducedportions 20am inserted in the enlargei'nents' 21of theibores ofthe sleeves 10.

The Supporting forks 6 have their. arms; 22 and 23 which extend npwa dl from e yoke of the fork, provided J with tapering' bores 24:, in which areiotatably seatedhthe" frusto-conically shaped portions 25, of .the bifurcated :roller supports 26. The" roller supports 26 have their terminal ends which project from the smaller ends of the frustoeonically shaped portions 25, provided with screw threads upon which are mounted nuts 27 for securely holding the roller supporting arms Within the arms 22 and 23 of the supporting fork 16. The arms 28 and 29 formed by the bifurcating of one of the ends of the roller support 26 have stub shafts 30 seated in openings 31 extending therethrough. The stub shafts 30 have rollers 32 and 33 rotatably mounted thereupon between the arms 28 and 29 of the supporting arm 26. The rollers 32 and 33 form the roller dies through which the wire or metallic rods being straightened pass, and by the provision of the frusto-conical portions 25 of the roller supporting arms, the angle of the axis of the rollers may be adjusted to regulate the speed of travel or the speed of feeding of the wire or rods through the machine, during the operation of the latter.

In Fig. 8 of the drawings a diagrammatic view is shown illustrating the manner of mounting the rolls at an angle to the longitudinalaxis of the frame 5, during the operation of the machine. The rollers are disposed, during the operation of the ma chine, so that their central axis which is designated by the dotted lines A. and B respectively in Fig. 8 extends at acute angles to the central longitudinal axis of the machine which is indicated by the line C.

The tension supporting forks 16 have wire or rod guides 40 secured thereto as at 41. The rod guides 40 constitute supports 42 which have the wire guides proper 43 secured to their upper ends and disposed at an angle to the vertical lines of the l supports. The wire guides proper 43 are sub stantially one-half of a hollow frusto-coni cal member and they have their small or reduced ends leading to the rollers 32 and 33 as is clearly shown in Fig. 3 of the draw- 111S.

its will be seen by reference to Fig. 1 of the drawings, the frame 5 has any desired number of roller dies and the necessary parts for supporting and adjusting them connected thereto and arranged in staggered relation along the longitudinal axis of the frame.

The frame 5 has projections 45 formed thereupon and extending inwardly, being disposed about the central axis of the frame and provided with bores extending therethrough, in which are seatedBabbitt metal or other suitable non-abrazing sleeves 46. The sleeves 46 extend through the hollow shanks 3 and 4 and are securely held in place by set screws 47 which are inserted through the projections or collars 45 and engage the surface of the sleeves adjacent their terminal ends. The pillow block 2 has a projection 48 formed thereupon,

which is similar in construction to the projections 45, having a set screw 49 adjustably mounted therein for engagement with the end of the sleeve 46 which is mountd within the hollow shaft 4. The hollow shaft 3 extends through the pillow block 1 and has a pulley 50 mounted upon its outer end, which pulley is provided for the transmission of rotary power to the frame 5, from any suitable power supply source.

In the operation of the improved wire straightening and planishing machine, the metallic rod or wire to be straightened is placed upon a reel behind the feeding end of the machine. The sleeves 10 are properly spaced in the horizontal slots 8, in accordance with the diameter of wire or the rod and securely held therein by the adjustment of the set screws 12. The tension supporting forks 16 are raised and locked in the proper position, so that the roller dies alternately project beyond the longitudinal axis of the frame, in opposite directions, so as to spring or flex the rod or wire passing through the machine, from side to side to the limit of its elasticity. The machine is then started causing the frame 5 to rotate and the end of the wire or rod to be straight ened is introduced through one of the hollow bushings and directed by one of the guides into the first roller die, which lifts the rod or wire from further contact with the guides. The guide next thereto, then deflects the end into the second roller die and so on successively until it passes out through the hollow bushing at the delivery end of the machine. The rotary motion of the frame 5 is imparted to the rollers 32 and 33 through the contact of the convex surfaces of the rollers with the rod or wire, which latter is prevented from turning by the coil on the reel and the inertia of its overhang. The axis-of each pair of convex rollers in the roller dies being set at an angle to each other and in a plane parallel to that of the wings, they will roll spirally around the rod or wireas the frame revolves, and their traction pushes or feeds the wire through the machine at the de sired rate of speed, at the same time, the contact of the hardened convex surfaces of the rotating rollers moves and planishes the rod or wire. The roller dies being stag gered along the longitudinal axis of the frame, flex the rod or wire, in all directions and thus straighten it. The depression between the pair of rollers forming the roller dies keeps the rod or wire from slipping off center, and any required degree of polish may be obtained by regulating the speed of feed of the wire through the machine, by altering the angle at which the axis of the rollers are arranged in comparison with the longitudinal axis of the frame, the slower the feeding of the wire through the machine, the higher and more efficient the polishing thereof will be.

From the foregoing description taken in connection with the accompanying drawings the advantages of the construction and of the method of operation of the improved wire straightening and planishing machine, will be readily apparent to those skilled in the art to which this invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construction, combination and arrangement of parts may be altered to suit practical con-- ditions provided such alterations are comprehended within the scope of what is claimed.
